PGC 128500
A magnitude 15(?) spiral galaxy (type Sbc? pec?) in
Phoenix (RA 01 09 42.9, Dec -55 36 21)
Physical Information: Based on a recessional velocity of 15495 km/sec, a straightforward calculation indicates that PGC 128500 is about 720 million light years away. However, for objects at such distances we should take into account the expansion of the Universe during the time it took their light to reach us. Doing that shows that the galaxy was about 680 million light years away at the time the light by which we see it was emitted, about 695 million years ago (the difference between the two numbers being due to the expansion of the intervening space during the light-travel time). Given that and its apparent size of about 0.6 by 0.3 arcmin, the galaxy is about 115 to 120 thousand light years across.
